Performance Issue Fixes Underway

Thank you for playing Pokémon Sleep!
The game is currently experiencing the following performance issues.
• Under certain circumstances, Error 028002 appearing and returning the app to the title screen when a large amount of ingredients was used for cooking.
The cooking pot’s capacity can be increased by up to 200 through the effects of the Main Skill Cooking Power-Up S. This bug occurred when more ingredients were used for cooking. There are plans to implement a notification that appears if the Main Skill is triggered when the cooking pot has reached maximum capacity, to explain that the skill cannot be used.
The conditions that lead to this bug are as follows.
Using more than the following amount of ingredients for cooking:
• (Cooking pot capacity × 2 [only when triggered by End-of-Week Bonus] + 200 [maximum capacity increase from Cooking Power-Up S]) × 1.5 (only when using a Good Camp Ticket)
For example, with a pot capacity of 33, the End-of-Week Bonus triggered, the capacity increased by the maximum of 200, and a Good Camp Ticket in use:
(33 × 2 + 200) × 1.5 = 399
In this case, you can avoid triggering the bug by using 399
ingredients or fewer.
Until the bug fix is complete, we ask that players take care not to use more ingredients than the above during cooking.
The following issue has been resolved along with the server update.
• Effects from the Helping Bonus not being reflected
This is scheduled to be fixed soon with a server update.
The following issue has been resolved as of version 1.0.9.
• Strength Gained displayed as 0 when a recipe at max level (50) was cooked
This was displayed as 0, but the correct amount of Strength was gained.
• Adjustments based on Pokémon Natures not being reflected when using candies to gain EXP
This is scheduled to be fixed in late September.
We are continuing to look into the situation and working on fixes.
Note: The following bug has already been fixed with a server update.
• Pokémon recovering over 100 Energy from sleep at the end of the week (most often from sleep between Sunday and Monday)
We sincerely apologize for the inconvenience.
We hope you continue to enjoy Pokémon Sleep!
